@philipma1957, or anyone with experience.
At this rate, since I'm using 600W'ish, can I run two SP20's off one (120v) EVGA 1300 G2? Safely? I recall you trying that somewhere in the thread, but don't remember the results, if any?
If so, how do I hook it up if I only have two more VGA red slots off the back?
I run two SP20s off of a single EVGA 1300 G2. Actually I run 6 of mine that way, I run two volt settings via the crontab because of heat/noise and electric cost issues during the day. They've been running like this for two months now without a single issue. Here are my volt settings:

FAN:0 VS0:605 VS1:615 VS2:605 VS3:615 VMAX:620 AC0:120 AC1:140 AC2:120 AC3:140 DC_AMP:170
miner-FL1451099043# cat mg_custom_mode_night
FAN:0 VS0:640 VS1:660 VS2:640 VS3:660 VMAX:665 AC0:160 AC1:180 AC2:160 AC3:180 DC_AMP:170
During the day 900GH/sec I'm using around 430W at the wall
At night I get 1.2TH/sec and I'm using around 610 at the wall
There are 6 outputs on the back of the PSU, I use one of their "double cables" and plug those into loops 1 and 3 (AC0 and AC2 internally) so I'm sending a little less power down that wire just to make sure I don't have overdraw issues down a single line.
